TODO

Important, before production release

• Add firebase creds to circleci and heroku so develop branch builds
• Check the mailservice if has been successful on their side
• Improve / fix request validation
• Improve error handling
• Improve test coverage, setup mock db, setup more mocks and tests

Nice to have:

• potentially break apart SendMailController, as it may have too many responsibilities
• performance; add a db index on the 'status' field so pending message lookup is faster and/or move successful messages elsewhere
• compilation instead of ts-node?
• Have a base MailService class that each mail service extends
• Add authentication
• Support for sending HTML emails (handlebars templates or something would be nice?)
• investigate using firebase feature .setWithPriority() and .orderByPriority()
